Zoeller Engineered Products offers a selection of submersible solids handling pumps in sizes from 1 to 100 hp. Their finned castings, oil filled housings and non-overloading windings enable the motor to maintain a low operating temperature when facing the harshest of conditions. These pumps are available with a 2.5-, 3- or 4-in. solids handling capacity and can use a semi-open, enclosed or vortex impeller. The discharge sizes range from 3 to 6 in. The pumps are available with standard or explosion-proof motor, all having an inverter duty option.
